Full level limit switch

• Based on a PTC with switchable functions
• With a probe as a filling limit switch: Immersion and surfacing cause switching of the relays
• With two probes as filling and extraction control:
-Set inner switch to “fill”
- The relay switches on when the min. probe is heated up
- Switch it off by immersing the max. probe
